Pnp/Pci Configurations - MSI 915G Neo3-FIR User Manual

This section describes configuring the PCI bus system and PnP (Plug & Play) feature.
PCI, or Peripheral Component Interconnect, is a system which allows I/O devices to
operate at speeds nearing the speed the CPU itself uses when communicating with
its special components. This section covers some very technical items and it is
strongly recommended that only experienced users should make any changes to the
default settings.
Init Display First
This setting specifies which VGA card is your primary graphics adapter. Setting
options are:
[PCI Slot] The system initializes the PCI Graphic card first. If a PCI Graphic card
is not available, it will initialize the PCI Express graphic.
[Onboard] The system initializes the Onboard Graphic card first.
[PCI -E] The system initializes the PCI Express graphic first. If a PCI Express
graphic card is not available, it will initialize the PCI graphic card.
PCI Slot1~4 IRQ
These items specify the IRQ line for each PCI slot. Setting options: [3], [4], [5], [7], [9],
[10], [11], [12], [14], [15], [Auto]. Selecting [Auto] allows BIOS to automatically deter-
mine the IRQ line for each PCI slot.
**PCI Express relative items**
M aximum Payload Size
This item allows you to set the maximum TLP (transaction layer packet) payload size
for the PCI Express devices. Setting options: [128], [256], [512], [1024], [2048], [4096].
